(*) There are still some OOM possibilities on writeback in themessenger library. It's possible to avoid this with the careful useof mempools, but I'd like to avoid doing so until it's clear theprotocol isn't going to change further.

The client seems to be quite stable in a single mds, no snapshotscenario (including recovery from mds, osd restarts). Thoroughtesting of snapshots and multiple MDSs is coming next. Clientauthentication (beyond the current host ip checking) is the other mainitem on the client todo list.

As always, I'm very interested in hearing what people would like tosee for this to be merged.
